Three neutral polar compounds (urea, thiourea, and xanthine) are separated on a Primesep S HILIC cation-exchange column with LC/MS compatible mobile phase. The retention time is controlled by the amount of acetonitrile in the mobile phase.
The Primesep family of mixed-mode columns offers a wide variety of stationary phases, boasting unprecedented selectivity in the separation of a broad array of chemical compounds across multiple applications. Corresponding Primesep guard columns, available with all stationary phases, do not require holders. SIELC provides a method development service available to all customers.
